In this paper, a novel global search optimization algorithm, Multi-Simplex Algorithm (MSA), is proposed. The MSA is the stochastic algorithm that utilizes the reflection operator of Simplex Method with scattered particles. Its effectiveness has been verified by applied on optimal design of Interior Permanent Magnet Synchronous Machine (IPMSM) aiming for reduction of Total Harmonic Distortion (THD)...
In this paper, design characteristics which maintain wide Constant Power Speed Range(CPSR) are analyzed. In order to analyze CPSR characteristics, two types of IPMSM which have different magnet topology are employed. Through comparison of torque-power curve and voltage limit ellipse, the design method for IPMSM maintaining wide CPSR is proposed.
In this paper, Genetic Algorithm (GA) based on Building Block (BB) identification is applied to optimal design of Interior Permanent Magnet Synchronous Motor (IPMSM). BBs on IPMSM design variables are identified using the proposed algorithm based on nonlinearity check by perturbation. Consequently, BB information regarding the design of IPMSM is proposed and the performance of the proposed algorithm...
In this study, we propose a novel intelligent particle swarm optimization(PSO). In case of PSO, when particles approach to optimum point, particles roam near global optimum. Therefore, PSO takes unnecessary function call and long convergence time. In order to solve these problems, we propose distance based intelligent particle swarm optimization(DbIPSO). DbIPSO calculate distance of every particle...
Optimal design of Permanent Magnet Synchronous Machine (PMSM) based on Finite Element Analysis (FEA) calls for huge computational time for high accuracy. Therefore, it is essential to select appropriate optimization algorithm. This paper presents the principal component optimization based on principal component analysis with mesh adaptive direct search to improve computation time and reliability of...
Novel analysis and design methodology using the newly adopted synthetic flux linkage for interior permanent-magnet (PM) synchronous motors (IPMSMs) with a multilayered PM have been proposed. In addition, cross magnetization between the and axes in the IPMSM is taken into account via the proposed synthetic flux linkage, which can be identified numerically and experimentally. It is validated with...
